Answer:
Given Mass of4.5kg the object =4.5kg Velocity = 0.9 m/s Momentum of the object is calculated using P=mv =4.5×0.9=4.05kgm/s =
Step-by-step explanation:
Mass of4.5kg the object =4.5kg Velocity = 0.9 m/s Momentum of the object is calculated using P=mv =4.5×0.9=4.05kgm/s
Answer:
Given that,
Mass m=1000kg
Speed v
1
=36km/h=10m/s
Speed v
2
=108km/h=30m/s
We know that,
The change in momentum
ΔP=m(Δv)
ΔP=m×(v
2
−v
1
)
ΔP=1000×(30−10)
ΔP=2×10
4
kgm/s
Hence, the change in momentum is 2×10
4
kgm/s
